You can do this using the splat operator:
some_func(*params)
This causes the function to receive each list item as a separate parameter. There's a description here: http://docs.python.org/tutorial/controlflow.html#unpacking-argument-lists
There is no such syntax in SQL Server, though CREATE TABLE AS ... SELECT
does exist in PDW. In SQL Server you can use this query to create an empty table:
SELECT * INTO schema.newtable FROM schema.oldtable WHERE 1 = 0;
(If you want to make a copy of the table including all of the data, then leave out the WHERE
clause.)
Note that this creates the same column structure (including an IDENTITY column if one exists) but it does not copy any indexes, constraints, triggers, etc.
for color in ['r', 'b', 'g', 'k', 'm']:
plot(x, y, color=color)
I use 3 lines to do this job, so consider $s as your "stuff"...
$s=str_replace(chr(10),'',$s);
$s=str_replace(chr(13),'',$s);
$s=str_replace("\r\n"),'',$s);
for (Map.Entry<String, ArrayList<Integer>> entry : map.entrySet()) {
System.out.println( entry.getKey());
System.out.println( entry.getValue());//Returns the list of values
}
You should be able to do something like this:
byte[] bitmap = GetYourImage();
using(Image image = Image.FromStream(new MemoryStream(bitmap)))
{
image.Save("output.jpg", ImageFormat.Jpeg); // Or Png
}
Look here for more info.
Hopefully this helps.
You can use the following SQL to compare both date and time -
Select * From temp where mydate > STR_TO_DATE('2009-06-29 04:00:44', '%Y-%m-%d %H:%i:%s');
Attached mysql output when I used same SQL on same kind of table and field that you mentioned in the problem-
It should work perfect.
My fellows,
In January 2019 I used a code made before:
<script type="text/javascript">
function imprimir() {
var divToPrint=document.getElementById("ConsutaBPM");
newWin= window.open("");
newWin.document.write(divToPrint.outerHTML);
newWin.print();
newWin.close();
}
</script>
To undestand: ConsutaBPM is a DIV which contains inside phrases and tables. I wanted to print ALL, titles, table, and others. The problem was when TRIED to print the TABLE...
The table mas be defined with BORDER and CELLPADDING:
<table border='1' cellpadding='1' id='Tablbpm1' >
It worked fine!!!
For what it's worth adding to the discussion... what I did that ended up helping me... Since the pipeline is run within a workspace within a docker image that is cleaned up each time it runs. I grabbed the credentials needed to perform necessary operations on the repo within my pipeline and stored them in a .netrc file. this allowed me to authorize the git repo operations successfully.
withCredentials([usernamePassword(credentialsId: '<credentials-id>', passwordVariable: 'GIT_PASSWORD', usernameVariable: 'GIT_USERNAME')]) {
sh '''
printf "machine github.com\nlogin $GIT_USERNAME\n password $GIT_PASSWORD" >> ~/.netrc
// continue script as necessary working with git repo...
'''
}
The below line is enough to display all columns from dataframe.
pd.set_option('display.max_columns', None)
Following options enable logging of all communication to the console (technically, you only need one of these, but that depends on the libraries you use, so setting all four is safer option). You can set it in the code like in example, or as command line parameter using -D or as environment variable as Upendra wrote.
System.setProperty("com.sun.xml.ws.transport.http.client.HttpTransportPipe.dump", "true");
System.setProperty("com.sun.xml.internal.ws.transport.http.client.HttpTransportPipe.dump", "true");
System.setProperty("com.sun.xml.ws.transport.http.HttpAdapter.dump", "true");
System.setProperty("com.sun.xml.internal.ws.transport.http.HttpAdapter.dump", "true");
System.setProperty("com.sun.xml.internal.ws.transport.http.HttpAdapter.dumpTreshold", "999999");

If you are trying to accessing config variable into controller than use
$this->config->item('{variable name which you define into config}');
If you are trying to accessing the config variable into outside the controller(helper/hooks) then use
$mms = get_instance();
$mms->config->item('{variable which you define into config}');
http://fetchak.com/ie-css3/ works for IE 6+. Use this if css3pie doesn't work for you.
With modern Git versions, the command to use would be:
git push -u origin <branch_name_test>
This will automatically set the branch name to track from remote and push in one go.
l=[['A', 1], ['B', 2], ['C', 3]]
d={}
for i,j in l:
d.setdefault(i,j)
print(d)
Set your header and footer position to "absolute" and that should do the trick. Hope it helps and good luck with your project!
The only way to remove the ADT plugin from Eclipse is to go to Help > About Eclipse/About ADT > Installation Details
.
Select a plug-in you want to uninstall, then click Uninstall...
button at the bottom.
If you cannot remove ADT from this location, then your best option is probably to start fresh with a clean Eclipse install.
If you have a Tensor
t, calling t.eval()
is equivalent to calling tf.get_default_session().run(t)
.
You can make a session the default as follows:
t = tf.constant(42.0)
sess = tf.Session()
with sess.as_default(): # or `with sess:` to close on exit
assert sess is tf.get_default_session()
assert t.eval() == sess.run(t)
The most important difference is that you can use sess.run()
to fetch the values of many tensors in the same step:
t = tf.constant(42.0)
u = tf.constant(37.0)
tu = tf.mul(t, u)
ut = tf.mul(u, t)
with sess.as_default():
tu.eval() # runs one step
ut.eval() # runs one step
sess.run([tu, ut]) # evaluates both tensors in a single step
Note that each call to eval
and run
will execute the whole graph from scratch. To cache the result of a computation, assign it to a tf.Variable
.
There are many ways to uninstall an MSI package. This is intended as a "reference".
In summary you can uninstall via: msiexec.exe, ARP, WMI, PowerShell, Deployment Systems such as SCCM, VBScript / COM Automation, DTF, or via hidden Windows cache folder, and a few other options presented below.
The first few paragraphs provide important MSI tidbits, then there are 14 sections with different ways to uninstall an MSI file. Puh.
"Babble, Babble - Over": Sections 1, 2 and 3 are the normal uninstall approaches (and hence recommended).
Personally I use option 3 or 5 from section 3
(both options with logging, but option 5 runs silently as well). If you are very busy, skip all the babble and go for one of these - it will get the job done.
If you have problems uninstalling altogether and are looking for an alternative to the deprecated MsiZap.exe and / or Windows Installer CleanUp Utility (MSICUU2.exe), you can try the new FixIt tool from Microsoft (or the international page). May apparently work for other install issues as well.
Newer list of cleanup approaches: Cleaning out broken MSI uninstalls.
If you think MSI and Windows Installer is more trouble than it's worth, you might want to read about the corporate benefits of using MSI files.
Installscript MSI setups generally come wrapped in a setup.exe file. To read more about the parameters to use for uninstalling such setups please see these links: setup.exe pdf reference sheet, Setup.exe and Update.exe Command-Line Parameters.
Some MSI files are installed as part of bundles via mechanism such as Burn (WiX Toolkit) or InstallShield Suite projects. This can make uninstall slightly different from what is seen below. Here is an example for InstallShield Suite projects.
Be aware that running uninstall silently or interactively can cause different results (!). For a rather lengthy description of why this is the case, please read this post: Uninstall from Control Panel is different from Remove from .msi
If you are unexpectedly asked for the original installation media when trying to uninstall, please read this answer: Why does MSI require the original .msi file to proceed with an uninstall? and perhaps also section 12 below for some important technical details.
If you got CCleaner or similar cleanup tools installed, perhaps jump to section 11.
If uninstall is failing entirely (not possible to run), see sections 12 & 13 below for a potential way to "undo" the installation using system restore and / or cleanup tools.
Using the original MSI
Using the old ARP Applet OR new Windows 8/10 Settings Interface
Just got to mention the normal approach(es) though it is obvious
ARP
= Add / Remove Programs Applet
(appwiz.cpl
)
Windows 10 Settings Interface
=> New shell for same operation
ARP:
Settings Interface (Windows 8 / 10):
Apps & Features
. Select entry and uninstall.ms-settings:appsfeatures
and press EnterUsing msiexec.exe command line (directly or via a batch file)
/qn
to make the uninstall run in silent mode. This is how an uninstall runs when triggered from the add/remove applet.Option 3.1: Basic interactive uninstall (access to original MSI file):
msiexec.exe /x "c:\filename.msi"
Option 3.2: Basic interactive uninstall via product GUID (no access to original MSI file - here is how to find the product GUID - same link as below):
msiexec.exe /x {11111111-1111-1111-1111-11111111111X}
Option 3.3: Interactive uninstall with verbose log file:
msiexec.exe /x "c:\filename.msi" /L*V "C:\msilog.log"
msiexec.exe /x {11111111-1111-1111-1111-11111111111X} /L*V "C:\msilog.log"
Option 3.4: Interactive uninstall with flushed, verbose log file (verbose, flush to log option - write log continuously, can be very slow):
msiexec.exe /x "c:\filename.msi" /L*V! "C:\msilog.log"
msiexec.exe /x {11111111-1111-1111-1111-11111111111X} /L*V! "C:\msilog.log"
The flush to log option makes the uninstall slow because the log file is written continuously instead of in batches. This ensures no log-buffer is lost if the setup crashes.
In other words, enable this option if your setup is crashing and there is no helpful information in your verbose log file. Remove the exclamation mark to turn off the flush to log option and the uninstall will be much quicker. You still get verbose logging, but as stated some log buffer could be lost.
Option 3.5 (recommended): Silent uninstall with verbose log file - suppress reboots (no flush to log - see previous option for what this means):
msiexec.exe /x "c:\filename.msi" /QN /L*V "C:\msilog.log" REBOOT=R
msiexec.exe /x {11111111-1111-1111-1111-11111111111X} /QN /L*V "C:\msilog.log" REBOOT=R
Quick Parameter Explanation (since I recommend this option):
/X = run uninstall sequence
/QN = run completely silently
/L*V "C:\msilog.log"= verbose logging at path specified
{11111111-1111-1111-1111-11111111111X} = product guid of app to uninstall
REBOOT=R = prevent unexpected reboot of computer
Again, how to find the product guid: How can I find the product GUID of an installed MSI setup? (for uninstall if you don't have the original MSI to specify in the uninstall command).
Top tip: If you create a log file for your uninstall, you can locate problems in the log by searching for "value 3". This is particularly useful for verbose files, because they are so, well, verbose :-).
How to find the product GUID for an installed MSI?
More information on logging from installsite.org: How do I create a log file of my installation? - great overview of different options and also specifics of InstallShield logging.
Msiexec (command-line options) - overview of the command line for msiexec.exe from MSDN. Here is the Technet version.
Using the cached MSI database in the super hidden cache folder
get-wmiobject Win32_Product | Format-Table Name, LocalPackage -AutoSize
Using
PowerShell
There is a similar, but more comprehensive PowerShell script available on MSDN. It allows uninstall to be run on several machines.
Entry added by Even Mien:
$app = Get-WmiObject -Class Win32_Product -Filter "Name = 'YOUR_APP'"
$app.Uninstall()
This approach will work, but accessing the WMI class Win32_Product will trigger a software consistency check which is very slow and in special circumstances it can cause an MSI self-repair to be triggered. See this article: Powershell Uninstall Script - Have a real headache
I have not tested this myself, but it appears $app.Uninstall() may run the UninstallString registered in the ARP applet's registry settings. This means it may run modify instead of uninstall in some cases.
Check this topic for more details and ways to uninstall via Powershell: How can I uninstall an application using PowerShell?
Using the .NET DTF Class Library
(part of the WiX toolkit) using Microsoft.Deployment.WindowsInstaller;
public static void Uninstall( string productCode)
{
Installer.ConfigureProduct(productCode, 0, InstallState.Absent, "REBOOT=\"R\"");
}
Using the
Windows Installer Automation API
Here is a community discussion of this option: Windows Installer Automation API community sample
The API can be accessed via script automation and C++ API calls (my post on serverfault.com)
The following source adapted from MSI expert Christopher Painter using VBScript:
Set installer = CreateObject("WindowsInstaller.Installer")
installer.InstallProduct "product.msi", "REMOVE=ALL REBOOT=ReallySuppress"
Set installer = Nothing
Here is another VBScript for uninstalling by GUID from Symantec: http://www.symantec.com/connect/downloads/uninstall-application-using-guid-registry
Using a
Windows Installer major upgrade
Using Deployment Systems / Remote Administration Systems
Using WMI - Windows Management Instrumentation
Win32_Product.Install
Win32_Product.Uninstall
Using a third-party tool such as
ccleaner
or similar
Using a cleanup tool such as
msizap
or similar
Using
system restore
("installation undo" - last resort IMHO)
Windows Installer Functions (C++)
For completeness I guess we should mention the core of it all - the down-to-the-metal way: the Win32 Windows Installer API functions. These are likely the functions used by most, if not all of the other approaches listed above "under the hood". They are primarily used by applications or solutions dealing directly with MSI as a technology.

If you're using Rails, you can just make an empty file in the public folder and use ajax to get that. Then parse the headers for the Date header. Files in the Public folder bypass the Rails stack, and so have lower latency.
You can get the comments of a particular method by using the ReflectionMethod class and calling ->getDocComment().

Declaring the field as 'final' will ensure that the field is a constant and cannot change. The difference comes in the usage of 'static' keyword.
Declaring a field as static means that it is associated with the type and not with the instances. i.e. only one copy of the field will be present for all the objects and not individual copy for each object. Due to this, the static fields can be accessed through the class name.
As you can see, your requirement that the field should be constant is achieved in both cases (declaring the field as 'final' and as 'static final').
Similar question is private final static attribute vs private final attribute

You're sending JSON-formatted data to a server which isn't expecting that format. You already provided the format that the server needs, so you'll need to format it yourself which is pretty simple.

What's new in Python 3.0 says:
All text is Unicode; however encoded Unicode is represented as binary data
If you want to ensure you are outputting utf-8, here's an example from this page on unicode in 3.0:
b'\x80abc'.decode("utf-8", "strict")
<select>
<optgroup label = "Choose One">
<option value ="sydney">Sydney</option>
<option value ="melbourne">Melbourne</option>
<option value ="cromwell">Cromwell</option>
<option value ="queenstown">Queenstown</option>

Add an EditText on top of your listview in its .xml layout file. And in your activity/fragment..
lv = (ListView) findViewById(R.id.list_view);
inputSearch = (EditText) findViewById(R.id.inputSearch);
// Adding items to listview
adapter = new ArrayAdapter<String>(this, R.layout.list_item, R.id.product_name, products);
lv.setAdapter(adapter);
inputSearch.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
// When user changed the Text
MainActivity.this.adapter.getFilter().filter(cs);
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) { }
@Override
public void afterTextChanged(Editable arg0) {}
});
The basic here is to add an OnTextChangeListener to your edit text and inside its callback method apply filter to your listview's adapter.
EDIT
To get filter to your custom BaseAdapter you"ll need to implement Filterable interface.
class CustomAdapter extends BaseAdapter implements Filterable {
public View getView(){
...
}
public Integer getCount()
{
...
}
@Override
public Filter getFilter() {
Filter filter = new Filter() {
@SuppressWarnings("unchecked")
@Override
protected void publishResults(CharSequence constraint, FilterResults results) {
arrayListNames = (List<String>) results.values;
notifyDataSetChanged();
}
@Override
protected FilterResults performFiltering(CharSequence constraint) {
FilterResults results = new FilterResults();
ArrayList<String> FilteredArrayNames = new ArrayList<String>();
// perform your search here using the searchConstraint String.
constraint = constraint.toString().toLowerCase();
for (int i = 0; i < mDatabaseOfNames.size(); i++) {
String dataNames = mDatabaseOfNames.get(i);
if (dataNames.toLowerCase().startsWith(constraint.toString())) {
FilteredArrayNames.add(dataNames);
}
}
results.count = FilteredArrayNames.size();
results.values = FilteredArrayNames;
Log.e("VALUES", results.values.toString());
return results;
}
};
return filter;
}
}
Inside performFiltering() you need to do actual comparison of the search query to values in your database. It will pass its result to publishResults() method.

This may be coming in Late but I think I figured out a better way to load external configurations especially when you run your spring-boot app using java jar myapp.war
instead of @PropertySource("classpath:some.properties")
The configuration would be loaded form the root of the project or from the location the war/jar file is being run from
public class Application implements EnvironmentAware {
public static void main(String[] args) throws Exception {
SpringApplication.run(Application.class, args);
}
@Override
public void setEnvironment(Environment environment) {
//Set up Relative path of Configuration directory/folder, should be at the root of the project or the same folder where the jar/war is placed or being run from
String configFolder = "config";
//All static property file names here
List<String> propertyFiles = Arrays.asList("application.properties","server.properties");
//This is also useful for appending the profile names
Arrays.asList(environment.getActiveProfiles()).stream().forEach(environmentName -> propertyFiles.add(String.format("application-%s.properties", environmentName)));
for (String configFileName : propertyFiles) {
File configFile = new File(configFolder, configFileName);
LOGGER.info("\n\n\n\n");
LOGGER.info(String.format("looking for configuration %s from %s", configFileName, configFolder));
FileSystemResource springResource = new FileSystemResource(configFile);
LOGGER.log(Level.INFO, "Config file : {0}", (configFile.exists() ? "FOund" : "Not Found"));
if (configFile.exists()) {
try {
LOGGER.info(String.format("Loading configuration file %s", configFileName));
PropertiesFactoryBean pfb = new PropertiesFactoryBean();
pfb.setFileEncoding("UTF-8");
pfb.setLocation(springResource);
pfb.afterPropertiesSet();
Properties properties = pfb.getObject();
PropertiesPropertySource externalConfig = new PropertiesPropertySource("externalConfig", properties);
((ConfigurableEnvironment) environment).getPropertySources().addFirst(externalConfig);
} catch (IOException ex) {
LOGGER.log(Level.SEVERE, null, ex);
}
} else {
LOGGER.info(String.format("Cannot find Configuration file %s... \n\n\n\n", configFileName));
}
}
}
}

Synchronized simply means that multiple threads if associated with single object can prevent dirty read and write if synchronized block is used on particular object. To give you more clarity , lets take an example :
class MyRunnable implements Runnable {
int var = 10;
@Override
public void run() {
call();
}
public void call() {
synchronized (this) {
for (int i = 0; i < 4; i++) {
var++;
System.out.println("Current Thread " + Thread.currentThread().getName() + " var value "+var);
}
}
}
}
public class MutlipleThreadsRunnable {
public static void main(String[] args) {
MyRunnable runnable1 = new MyRunnable();
MyRunnable runnable2 = new MyRunnable();
Thread t1 = new Thread(runnable1);
t1.setName("Thread -1");
Thread t2 = new Thread(runnable2);
t2.setName("Thread -2");
Thread t3 = new Thread(runnable1);
t3.setName("Thread -3");
t1.start();
t2.start();
t3.start();
}
}
We've created two MyRunnable class objects , runnable1 being shared with thread 1 and thread 3 & runnable2 being shared with thread 2 only. Now when t1 and t3 starts without synchronized being used , PFB output which suggest that both threads 1 and 3 simultaneously affecting var value where for thread 2 , var has its own memory.
Without Synchronized keyword
Current Thread Thread -1 var value 11
Current Thread Thread -2 var value 11
Current Thread Thread -2 var value 12
Current Thread Thread -2 var value 13
Current Thread Thread -2 var value 14
Current Thread Thread -1 var value 12
Current Thread Thread -3 var value 13
Current Thread Thread -3 var value 15
Current Thread Thread -1 var value 14
Current Thread Thread -1 var value 17
Current Thread Thread -3 var value 16
Current Thread Thread -3 var value 18
Using Synchronzied, thread 3 waiting for thread 1 to complete in all scenarios. There are two locks acquired , one on runnable1 shared by thread 1 and thread 3 and another on runnable2 shared by thread 2 only.
Current Thread Thread -1 var value 11
Current Thread Thread -2 var value 11
Current Thread Thread -1 var value 12
Current Thread Thread -2 var value 12
Current Thread Thread -1 var value 13
Current Thread Thread -2 var value 13
Current Thread Thread -1 var value 14
Current Thread Thread -2 var value 14
Current Thread Thread -3 var value 15
Current Thread Thread -3 var value 16
Current Thread Thread -3 var value 17
Current Thread Thread -3 var value 18
its simple to call a message box, so if you want to code behind or call function, I think it is better or may be not. There is a process, you can just use namespace
using system.widows.forms;
then, where you want to show a message box, just call it as simple, as in C#, like:
messagebox.show("Welcome");
i know this question is old, but hopefully it will help someone.
i found a great plugin for those who are using PyCharm IDE:
string-manipulation
that can easily escape double quotes (and many more...), this plugin is great for cases where you know what the string going to be.
for other cases, using json.dumps(string)
will be the recommended solution
str_to_escape = 'my string with "double quotes" blablabla'
after_escape = 'my string with \"double quotes\" blablabla'
I've always used the same approach as @guneysus to solve this problem, which is creating a script in the package.json file and use it running npm run script-name.
However, in the recent months I've been using npx and I love it.
For example, I downloaded an Angular project and I didn't want to install the Angular CLI globally. So, with npx installed, instead of using the global angular cli command (if I had installed it) like this:
ng serve
I can do this from the console:
npx ng serve
Here's an article I wrote about NPX and that goes deeper into it.

You can directly plot the lines you want by feeding the plot
command with the corresponding data (boundaries of the segments):
plot([x1, x2], [y1, y2], color='k', linestyle='-', linewidth=2)
(of course you can choose the color, line width, line style, etc.)
From your example:
import numpy as np
import matplotlib.pyplot as plt
np.random.seed(5)
x = np.arange(1, 101)
y = 20 + 3 * x + np.random.normal(0, 60, 100)
plt.plot(x, y, "o")
# draw vertical line from (70,100) to (70, 250)
plt.plot([70, 70], [100, 250], 'k-', lw=2)
# draw diagonal line from (70, 90) to (90, 200)
plt.plot([70, 90], [90, 200], 'k-')
plt.show()
The quick answer the the Question is no you can't, because of Java generic type erasure.
The longer answer would be that if you have created your list like this:
new ArrayList<SpideMan>(){}
Then in this case the generic type is preserved in the generic superclass of the new anonymous class above.
Not that I recommend doing this with lists, but it is a listener implementation:
new Listener<Type>() { public void doSomething(Type t){...}}
And since extrapolating the generic types of super classes and super interfaces change between JVMs, the generic solution is not as straight forward as some answers might suggest.

There are a couple of options there. The sample code is in Java, but a port to other languages should be straightforward.
WebElement myElement = driver.findElement(By.id("myDiv"));
WebElement parent = (WebElement) ((JavascriptExecutor) driver).executeScript(
"return arguments[0].parentNode;", myElement);
WebElement myElement = driver.findElement(By.id("myDiv"));
WebElement parent = myElement.findElement(By.xpath("./.."));
WebElement
Note: As you can see, for the JavaScript version you'll need the driver
. If you don't have direct access to it, you can retrieve it from the WebElement
using:
WebDriver driver = ((WrapsDriver) myElement).getWrappedDriver();
JPA is a layered API, the different levels have their own annotations. The highest level is the (1) Entity level which describes persistent classes then you have the (2) relational database level which assume the entities are mapped to a relational database and (3) the java model.
Level 1 annotations: @Entity
, @Id
, @OneToOne
, @OneToMany
, @ManyToOne
, @ManyToMany
.
You can introduce persistency in your application using these high level annotations alone. But then you have to create your database according to the assumptions JPA makes. These annotations specify the entity/relationship model.
Level 2 annotations: @Table
, @Column
, @JoinColumn
, ...
Influence the mapping from entities/properties to the relational database tables/columns if you are not satisfied with JPA's defaults or if you need to map to an existing database. These annotations can be seen as implementation annotations, they specify how the mapping should be done.
In my opinion it is best to stick as much as possible to the high level annotations and then introduce the lower level annotations as needed.
To answer the questions: the @OneToMany
/mappedBy
is nicest because it only uses the annotations from the entity domain. The @oneToMany
/@JoinColumn
is also fine but it uses an implementation annotation where this is not strictly necessary.

You need to have the 'data' array outside of the loop, otherwise it will get reset in every loop and also you can directly push the json. Find the solution below:-
var my_json;
$.getJSON("https://api.thingspeak.com/channels/"+did+"/feeds.json?api_key="+apikey+"&results=300", function(json1) {
console.log(json1);
var data = [];
json1.feeds.forEach(function(feed,i){
console.log("\n The details of " + i + "th Object are : \nCreated_at: " + feed.created_at + "\nEntry_id:" + feed.entry_id + "\nField1:" + feed.field1 + "\nField2:" + feed.field2+"\nField3:" + feed.field3);
my_json = feed;
console.log(my_json); //Object {created_at: "2017-03-14T01:00:32Z", entry_id: 33358, field1: "4", field2: "4", field3: "0"}
data.push(my_json);
//["2017-03-14T01:00:32Z", 33358, "4", "4", "0"]
});
console.log(data);
User JQuery is EmptyObject to check whether array is contains elements or not.
var testArray=[1,2,3,4,5];
var testArray1=[];
console.log(jQuery.isEmptyObject(testArray)); //false
console.log(jQuery.isEmptyObject(testArray1)); //true
I doing something to similar to wize but in my answer yo can change between the two fragments whenever you want. And with the wize answer I have some problems when changing the orientation of the screen an things like that. This is the PagerAdapter looks like:
public class MyAdapter extends FragmentPagerAdapter
{
static final int NUM_ITEMS = 2;
private final FragmentManager mFragmentManager;
private Fragment mFragmentAtPos0;
private Map<Integer, String> mFragmentTags;
private boolean isNextFragment=false;
public MyAdapter(FragmentManager fm)
{
super(fm);
mFragmentManager = fm;
mFragmentTags = new HashMap<Integer, String>();
}
@Override
public Fragment getItem(int position)
{
if (position == 0)
{
if (isPager) {
mFragmentAtPos0 = new FirstPageFragment();
} else {
mFragmentAtPos0 = new NextFragment();
}
return mFragmentAtPos0;
}
else
return SecondPageFragment.newInstance();
}
@Override
public int getCount()
{
return NUM_ITEMS;
}
@Override
public Object instantiateItem(ViewGroup container, int position) {
Object obj = super.instantiateItem(container, position);
if (obj instanceof Fragment) {
// record the fragment tag here.
Fragment f = (Fragment) obj;
String tag = f.getTag();
mFragmentTags.put(position, tag);
}
return obj;
}
public void onChange(boolean isNextFragment) {
if (mFragmentAtPos0 == null)
mFragmentAtPos0 = getFragment(0);
if (mFragmentAtPos0 != null)
mFragmentManager.beginTransaction().remove(mFragmentAtPos0).commit();
if (!isNextFragment) {
mFragmentAtFlashcards = new FirstPageFragment();
} else {
mFragmentAtFlashcards = new NextFragment();
}
notifyDataSetChanged();
}
@Override
public int getItemPosition(Object object)
{
if (object instanceof FirstPageFragment && mFragmentAtPos0 instanceof NextFragment)
return POSITION_NONE;
if (object instanceof NextFragment && mFragmentAtPos0 instanceof FirstPageFragment)
return POSITION_NONE;
return POSITION_UNCHANGED;
}
public Fragment getFragment(int position) {
String tag = mFragmentTags.get(position);
if (tag == null)
return null;
return mFragmentManager.findFragmentByTag(tag);
}
}
The listener I implemented in the adapter container activity to put it to the fragment when attaching it, this is the activity:
public class PagerContainerActivity extends AppCompatActivity implements ChangeFragmentListener {
//...
@Override
public void onChange(boolean isNextFragment) {
if (pagerAdapter != null)
pagerAdapter.onChange(isNextFragment);
}
//...
}
Then in the fragment putting the listener when attach an calling it:
public class FirstPageFragment extends Fragment{
private ChangeFragmentListener changeFragmentListener;
//...
@Override
public void onAttach(Activity activity) {
super.onAttach(activity);
changeFragmentListener = ((PagerContainerActivity) activity);
}
@Override
public void onDetach() {
super.onDetach();
changeFragmentListener = null;
}
//...
//in the on click to change the fragment
changeFragmentListener.onChange(true);
//...
}
And finally the listener:
public interface changeFragmentListener {
void onChange(boolean isNextFragment);
}

This works in Python 3.x and 2.x:
# Fix Python 2.x.
try: input = raw_input
except NameError: pass
print("Hi " + input("Say something: "))
You can use this function:
function mapMap(map, fn) {
return new Map(Array.from(map, ([key, value]) => [key, fn(value, key, map)]));
}
usage:
var map1 = new Map([["A", 2], ["B", 3], ["C", 4]]);
var map2 = mapMap(map1, v => v * v);
console.log(map1, map2);
/*
Map { A ? 2, B ? 3, C ? 4 }
Map { A ? 4, B ? 9, C ? 16 }
*/
Some of the code looks a bit complex to me. This is very simple code to select only the used rows in two discontiguous columns D and H. It presumes the columns are of unequal length and thus more flexible vs if the columns were of equal length.
As you most likely surmised 4=column D and 8=column H
Dim dlastRow As Long
Dim hlastRow As Long
dlastRow = ActiveSheet.Cells(Rows.Count, 4).End(xlUp).Row
hlastRow = ActiveSheet.Cells(Rows.Count, 8).End(xlUp).Row
Range("D2:D" & dlastRow & ",H2:H" & hlastRow).Select
Hope you find useful - DON'T FORGET THAT COMMA BEFORE THE SECOND COLUMN, AS I DID, OR IT WILL BOMB!!
You can try adding:
#aboutDescription
{

You need to wrap you image source path within {}

new flutter sdk since after integration of web and desktop support you need to specify individually like this
TextFormField(

keyboardType: inputType,
decoration: new InputDecoration(
border: InputBorder.none,
focusedBorder: InputBorder.none,
enabledBorder: InputBorder.none,
errorBorder: InputBorder.none,
disabledBorder: InputBorder.none,
contentPadding:
EdgeInsets.only(left: 15, bottom: 11, top: 11, right: 15),
hintText: "Hint here"),
)
This is somewhat of an extension to the answer when the comment line is too long to fit on a line (above 80 chars or whatever). If the comment is too long and text needs to wrap, it's better to keep it under control (rather than use the editor's text wrap feature). This plugin Rewrap helps do just that https://marketplace.visualstudio.com/items?itemName=stkb.rewrap&ssr=false#review-details
Install the plugin in VS Code, select the text comment, comment it using one of the right methods described in the answers (Ctrl + / is easiest) and then once it's commented, press Alt + Q and this will split the text to multiple lines and also comment it. Found it pretty useful. Hope this helps someone :)
You can have a datetime picker when using matInput
with type datetime-local
like so:
<mat-form-field>
<input matInput type="datetime-local" placeholder="start date">
</mat-form-field>
You can click on each part of the placeholder to set the day, month, year, hours,minutes and whether its AM or PM.
For the question
How can i run a jar file in command prompt but with arguments
.
To pass arguments to the jar file at the time of execution
java -jar myjar.jar arg1 arg2
In the main() method of "Main-Class" [mentioned in the manifest.mft file]of your JAR file. you can retrieve them like this:
String arg1 = args[0];
String arg2 = args[1];
I use bootstrap 3.x as well and the following code fore responsive youtube video embedding works like charm for me:
.videoWrapperOuter {
max-width:640px;
margin-left:auto;
margin-right:auto;
}
.videoWrapperInner {
float: none;
clear: both;
width: 100%;
position: relative;
padding-bottom: 50%;
padding-top: 25px;
height: 0;
}
.videoWrapperInner iframe {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
<div class="videoWrapperOuter">
<div class="videoWrapperInner">
<iframe src="//www.youtube.com/embed/C6-TWRn0k4I"
frameborder="0" allowfullscreen></iframe>
</div>
</div>
I gave a similiar answer on another thread (Shrink a YouTube video to responsive width), but I guess my answers can help here as well.
I was getting this error once and took many of the approaches here.
My issues was that I had two app.listen(3000);
calls in the same app.js script. The first app.listen() succeeded where the second threw the error.
Another useful command I came across that helped me debug was sudo fuser -k 3000/tcp
which will kill any rogue processes you might have started (some processes may restart, e.g. if run with forever.js, but it was useful for me).
I solved it doing
run devenv /resetuserdata
in this path:
[x64] C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE
I assume that in x86 it works in this path:
[x86] C:\Program Files\Microsoft Visual Studio 14.0\Common7\IDE
If you don't use Java 8 and you don't want to use a explicit loop for some reason, try MapUtils.populateMap
from Apache Commons.
Say you have a list of Pair
s.
List<ImmutablePair<String, String>> pairs = ImmutableList.of(
new ImmutablePair<>("A", "aaa"),
new ImmutablePair<>("B", "bbb")
);
And you now want a Map of the Pair
's key to the Pair
object.
Map<String, Pair<String, String>> map = new HashMap<>();
MapUtils.populateMap(map, pairs, new Transformer<Pair<String, String>, String>() {
@Override
public String transform(Pair<String, String> input) {
return input.getKey();
}
});
System.out.println(map);
gives output:
{A=(A,aaa), B=(B,bbb)}
That being said, a for
loop is maybe easier to understand. (This below gives the same output):
Map<String, Pair<String, String>> map = new HashMap<>();
for (Pair<String, String> pair : pairs) {
map.put(pair.getKey(), pair);
}
System.out.println(map);
You can write:
python
import keras
keras.__version__
You can find examples for writing OAuth clients here:
In your case you can't just use default or base classes for everything, you have a multiple classes Implementing OAuth2ProtectedResourceDetails
. The configuration depends of how you configured your OAuth service but assuming from your curl connections I would recommend:
@EnableOAuth2Client
@Configuration
class MyConfig{
@Value("${oauth.resource:http://localhost:8082}")
private String baseUrl;
@Value("${oauth.authorize:http://localhost:8082/oauth/authorize}")
private String authorizeUrl;
@Value("${oauth.token:http://localhost:8082/oauth/token}")
private String tokenUrl;
@Bean
protected OAuth2ProtectedResourceDetails resource() {
ResourceOwnerPasswordResourceDetails resource;
resource = new ResourceOwnerPasswordResourceDetails();
List scopes = new ArrayList<String>(2);
scopes.add("write");
scopes.add("read");
resource.setAccessTokenUri(tokenUrl);
resource.setClientId("restapp");
resource.setClientSecret("restapp");
resource.setGrantType("password");
resource.setScope(scopes);
resource.setUsername("**USERNAME**");
resource.setPassword("**PASSWORD**");
return resource;
}
@Bean
public OAuth2RestOperations restTemplate() {
AccessTokenRequest atr = new DefaultAccessTokenRequest();
return new OAuth2RestTemplate(resource(), new DefaultOAuth2ClientContext(atr));
}
}
@Service
@SuppressWarnings("unchecked")
class MyService {
@Autowired
private OAuth2RestOperations restTemplate;
public MyService() {
restTemplate.getAccessToken();
}
}
Do not forget about @EnableOAuth2Client
on your config class, also I would suggest to try that the urls you are using are working with curl first, also try to trace it with the debugger because lot of exceptions are just consumed and never printed out due security reasons, so it gets little hard to find where the issue is. You should use logger
with debug
enabled set.
Good luck
I uploaded sample springboot app on github https://github.com/mariubog/oauth-client-sample to depict your situation because I could not find any samples for your scenario .
suppose the multiSelect is the Multiple-Select-Element, just use its selectedOptions Property:
//show all selected options in the console:
for ( var i = 0; i < multiSelect.selectedOptions.length; i++) {
console.log( multiSelect.selectedOptions[i].value);
}
Here it is: http://jsfiddle.net/tQyvp/
Here's the code if you don't like going to jsfiddle:
html
<input id="myinputfield" value="This is some text" type="button">?
Javascript:
$('body').on('click', '#myinputfield', function(){
var textField = $('#myinputfield');
textField.val(textField.val()+' after clicking')
});?
Closing and Re-Importing project worked for me.
Image can not be shown until it serves from any server. so you need to upload the image to your server to show its preview.
I was facing a similar problem when I was trying to do a custom view for a ListView
.
I solved it simply by doing this:
public View getView(int i, View view, ViewGroup viewGroup) {
// Gets the inflater
LayoutInflater inflater = LayoutInflater.from(this.contexto);
// Inflates the layout
ConstraintLayout cl2 = (ConstraintLayout)
inflater.inflate(R.layout.custom_list_view, viewGroup, false);
//Insted of calling just findViewById, I call de cl2.findViewById method. cl2 is the layout I have just inflated.
TextView tv1 = (TextView)cl2.findViewById(cl2);
I'll try to keep this short, I've done this a few months ago for a game I was trying to build, it does a UDP "Client-Server" connection that acts like TCP, you can send (message) (message + object) using this. I've done some testing with it and it works just fine, feel free to modify it if needed.
I got this error using Maven, and I discovered the solution.
Error: Could not find or load main class com.mycompany.testapifactory.Main
I'm using java JDK version 1.7 on Linux, my pom.xml
file was the default generated by Netbeans and I was using these commands to compile, which do work fine with a normal hello-world java application:
mvn clean compile
java -jar target/TestAPIFactory-1.0-SNAPSHOT.jar com.mycompany.testapifactory.Main
What happened:
It turns out my problem was that my Main method was extending something Exotic like this:
public class Main extends SomeExoticLibraryClass{
public static void main(String[] args){
//...
}
}
It was this extending of the main class that caused the above error.
TLDR solution:
Make sure your main class isn't extending any 3rd party classes. Refactor those out and away into their own classes. That error message is awful, and requires process of elimination to find out what to do.
Adding on, you can turn off the creation of vshost files for your Release build configuration and have it enabled for Debug.

Excerpt from MSDN How to: Disable the Hosting Process
Calls to certain APIs can be affected when the hosting process is enabled. In these cases, it is necessary to disable the hosting process to return the correct results.
To disable the hosting process
When the hosting process is disabled, several debugging features are unavailable or experience decreased performance. For more information, see Debugging and the Hosting Process.
In general, when the hosting process is disabled:
- The time needed to begin debugging .NET Framework applications increases.
- Design-time expression evaluation is unavailable.
- Partial trust debugging is unavailable.
Basically: assign a keyup
handler to the <textarea>
element, in it count the length of the <textarea>
and write the count to a separate <div>
if its length is shorter than a minimum value.
Here's is an example-
var min = 15;_x000D_
document.querySelector('#tst').onkeyup = function(e){_x000D_
document.querySelector('#counter').innerHTML = _x000D_
this.value.length < min _x000D_
? (min - this.value.length)+' to go...'_x000D_
: '';_x000D_
}_x000D_
_x000D_
body {font: normal 0.8em verdana, arial;}_x000D_
#counter {color: grey}
_x000D_
<textarea id="tst" cols="60" rows="10"></textarea>_x000D_
<div id="counter"></div>

If you are use nginx try this
#Control-Allow-Origin access
# Authorization headers aren't passed in CORS preflight (OPTIONS) calls. Always return a 200 for options.
add_header Access-Control-Allow-Credentials "true" always;
add_header Access-Control-Allow-Origin "https://URL-WHERE-ORIGIN-FROM-HERE " always;

Be wary of using ExpectedException, as it can lead to several pitfalls as demonstrated here:
http://geekswithblogs.net/sdorman/archive/2009/01/17/unit-testing-and-expected-exceptions.aspx
And here:
http://xunit.github.io/docs/comparisons.html
If you need to test for exceptions, there are less frowned upon ways. You can use the try{act/fail}catch{assert}
method, which can be useful for frameworks that don't have direct support for exception tests other than ExpectedException
.
A better alternative is to use xUnit.NET, which is a very modern, forward looking, and extensible unit testing framework that has learned from all the others mistakes, and improved. One such improvement is Assert.Throws
, which provides a much better syntax for asserting exceptions.
You can find xUnit.NET at github: http://xunit.github.io/
You are incorrectly using the super
and this
keyword. Here is an example of how they work:
class Animal {
public name: string;
constructor(name: string) {
this.name = name;
}
move(meters: number) {
console.log(this.name + " moved " + meters + "m.");
}
}
class Horse extends Animal {
move() {
console.log(super.name + " is Galloping...");
console.log(this.name + " is Galloping...");
super.move(45);
}
}
var tom: Animal = new Horse("Tommy the Palomino");
Animal.prototype.name = 'horseee';
tom.move(34);
// Outputs:
// horseee is Galloping...
// Tommy the Palomino is Galloping...
// Tommy the Palomino moved 45m.
Explanation:
super.name
, this refers to the prototype chain of the object tom
, not the object tom
self. Because we have added a name property on the Animal.prototype
, horseee will be outputted.this.name
, the this
keyword refers to the the tom object itself. move
method of the Animal base class. This method is called from Horse class move method with the syntax super.move(45);
. Using the super
keyword in this context will look for a move
method on the prototype chain which is found on the Animal prototype.Remember TS still uses prototypes under the hood and the class
and extends
keywords are just syntactic sugar over prototypical inheritance.
rekaszeru
I noticed that you commented in 2011 but i thought i should post this answer anyway, in case anyone needs to "replace the original string" and runs into this answer ..
Im using a EditText as an example
// GIVE TARGET TEXT BOX A NAME
EditText textbox = (EditText) findViewById(R.id.your_textboxID);
// STRING TO REPLACE
String oldText = "hello"
String newText = "Hi";
String textBoxText = textbox.getText().toString();
// REPLACE STRINGS WITH RETURNED STRINGS
String returnedString = textBoxText.replace( oldText, newText );
// USE RETURNED STRINGS TO REPLACE NEW STRING INSIDE TEXTBOX
textbox.setText(returnedString);
This is untested, but it's just an example of using the returned string to replace the original layouts string with setText() !
Obviously this example requires that you have a EditText with the ID set to your_textboxID
You can also use python's requests library instead.
import requests
url = 'http://www.quandl.com/api/v1/datasets/FRED/GDP.json'
response = requests.get(url)
dict = response.json()
Now you can manipulate the "dict" like a python dictionary.
type log.txt
But that will give you the whole file. You could change it to:
echo %date%, %time% >> log.txt
echo %date%, %time% > log_last.txt
...
type log_last.txt
to get only the last one.
How I did it with a pivot in dynamic sql (#AccPurch was created prior to this)
DECLARE @sql AS nvarchar(MAX)
declare @Month Nvarchar(1000)
--DROP TABLE #temp
select distinct YYYYMM into #temp from #AccPurch AS ap
SELECT @Month = COALESCE(@Month, '') + '[' + CAST(YYYYMM AS VarChar(8)) + '],' FROM #temp
SELECT @Month= LEFT(@Month,len(@Month)-1)
SET @sql = N'SELECT UserID, '+ @Month + N' into ##final_Donovan_12345 FROM (
Select ap.AccPurch ,
ap.YYYYMM ,
ap.UserID ,
ap.AccountNumber
FROM #AccPurch AS ap
) p
Pivot (SUM(AccPurch) FOR YYYYMM IN ('+@Month+ N')) as pvt'
EXEC sp_executesql @sql
Select * INTO #final From ##final_Donovan_12345
DROP TABLE ##final_Donovan_12345
Select * From #final AS f
Now that the Web Audio API is here and gaining browser support, that could be a more robust option.
Zounds is a primitive wrapper around that API for playing simple one-shot sounds with a minimum of boilerplate at the point of use.
instanceof is a keyword that can be used to test if an object is of a specified type.
Example :
public class MainClass {
public static void main(String[] a) {
String s = "Hello";
int i = 0;
String g;
if (s instanceof java.lang.String) {
// This is going to be printed
System.out.println("s is a String");
}
if (i instanceof Integer) {
// This is going to be printed as autoboxing will happen (int -> Integer)
System.out.println("i is an Integer");
}
if (g instanceof java.lang.String) {
// This case is not going to happen because g is not initialized and
// therefore is null and instanceof returns false for null.
System.out.println("g is a String");
}
}
Here is my source.
Another similar solution:
>>> a=datetime.now()
>>> "%s:%s.%s" % (a.hour, a.minute, a.microsecond)
'14:28.971209'
Yes, I know I didn't get the string formatting perfect.
You can try Gson convertor, to get the exact conversion like json.stringify
val jsonString:String = jsonObject.toString()
val gson:Gson = GsonBuilder().setPrettyPrinting().create()
val json:JsonElement = gson.fromJson(jsonString,JsonElement.class)
val jsonInString:String= gson.toJson(json)
println(jsonInString)
I answered this question in another post:
How to get list of changed files since last build in Jenkins/Hudson
#!/bin/bash
set -e
job_name="whatever"
JOB_URL="http://myserver:8080/job/${job_name}/"
FILTER_PATH="path/to/folder/to/monitor"
python_func="import json, sys
obj = json.loads(sys.stdin.read())
ch_list = obj['changeSet']['items']
_list = [ j['affectedPaths'] for j in ch_list ]
for outer in _list:
for inner in outer:
print inner
"
_affected_files=`curl --silent ${JOB_URL}${BUILD_NUMBER}'/api/json' | python -c "$python_func"`
if [ -z "`echo \"$_affected_files\" | grep \"${FILTER_PATH}\"`" ]; then
echo "[INFO] no changes detected in ${FILTER_PATH}"
exit 0
else
echo "[INFO] changed files detected: "
for a_file in `echo "$_affected_files" | grep "${FILTER_PATH}"`; do
echo " $a_file"
done;
fi;
You can add the check directly to the top of the job's exec shell, and it will exit 0
if no changes are detected... Hence, you can always poll the top level for check-in's to trigger a build.
iif has always been available in VB, even in VB6.
Dim foo as String = iif(bar = buz, cat, dog)
It is not a true operator, as such, but a function in the Microsoft.VisualBasic namespace.
Please go to this quick example I've created jsFiddle. Hopefull it's easy to understand. You can use a wrapper
div with the width of the site to center align. The reason you must put width
is that so browser knows you are not going for a liquid layout.
Perhaps a more logical method would be to create a file (e.g. test.html), add some content and then try to set it as the index page:
DirectoryIndex test.html
For the most part, the .htaccess rule will override the Apache configuration where working at the directory/file level
There is a basic difference between .append()
and .after()
and .prepend()
and .before()
.
.append()
adds the parameter element inside the selector element's tag at the very end whereas the .after()
adds the parameter element after the element's tag.
The vice-versa is for .prepend()
and .before()
.
I think you actually want this:
>>> from subprocess import *
>>> command_stdout = Popen(['ls', '-l'], stdout=PIPE).communicate()[0]
>>> command_text = command_stdout.decode(encoding='windows-1252')
Aaron's answer was correct, except that you need to know which encoding to use. And I believe that Windows uses 'windows-1252'. It will only matter if you have some unusual (non-ASCII) characters in your content, but then it will make a difference.
By the way, the fact that it does matter is the reason that Python moved to using two different types for binary and text data: it can't convert magically between them, because it doesn't know the encoding unless you tell it! The only way YOU would know is to read the Windows documentation (or read it here).
Try reducing the range of the for loop to range(len(a)-1)
:
a = [0,1,2,3]
b = []
for i in range(len(a)-1):
b.append(a[i]+a[i+1])
print(b)
This can also be written as a list comprehension:
b = [a[i] + a[i+1] for i in range(len(a)-1)]
print(b)
In your controller, render the new
action from your create action if validation fails, with an instance variable, @car
populated from the user input (i.e., the params
hash). Then, in your view, add a logic check (either an if block around the form
or a ternary on the helpers, your choice) that automatically sets the value of the form fields to the params
values passed in to @car if car exists. That way, the form will be blank on first visit and in theory only be populated on re-render in the case of error. In any case, they will not be populated unless @car
is set.
For the latest version of Bitbucket (2016+), the download link can be found in the Download menu item.
Pre-2016
First method
In the Overview page of the repo, there is a link to download the project.
Second method
Go to Downloads -> Branches -> Download the branch that you want (as .zip, .gz or .bz2). There you'll find download links for all tags. The links will be in the format:
https://bitbucket.org/owner/repository/get/v0.1.2.tar.gz
By tweaking it a little bit, you can also have access to any revision by changing the tag to the commit hash:
https://bitbucket.org/owner/repository/get/A0B1C2D.tar.gz
I also had the same issue though am using MacOS. The issue is kind of bug. I solved this issue by repeatedly running the commands,
sudo npm cache clean --force
sudo npm uninstall
sudo npm install
One time it did not work but when I repeatedly cleaned the cache and after uninstalling npm, reinstalling npm, the error went off. I am using Angular 8 and this issue is common
TryParse is the best way for parse or validate in single line:
int nNumber = int.TryParse("InputString", out nNumber) ? nNumber : 1;

That's not a rounding ploblem, that is a display problem. A number doesn't contain information about significant digits; the value 2 is the same as 2.0000000000000. It's when you turn the rounded value into a string that you have make it display a certain number of digits.
You could just add zeroes after the number, something like:
var s = number.toString();
if (s.indexOf('.') == -1) s += '.';
while (s.length < s.indexOf('.') + 4) s += '0';
(Note that this assumes that the regional settings of the client uses period as decimal separator, the code needs some more work to function for other settings.)

When you have multiple if
conditions, numpy.select
is the way to go:

In [4098]: conditions = [df.A.eq(df.B), df.A.gt(df.B), df.A.lt(df.B)]
In [4096]: choices = [0, 1, -1]
In [4100]: df['C'] = np.select(conditions, choices)
In [4101]: df
Out[4101]:

Perhaps not 100% answering the question, but i stumbled onto this thread in the hope of solving a session problem when ajax-posting a fileupload from the assetmanager of the innovastudio editor. Eventually the solution was simple: they have a flash-uploader. Disabling that (setting
var flashUpload = false;
in asset.php) and the lights started blinking again.
As these problems can be very hard to debug i found that putting something like the following in the upload handler will set you (well, me in this case) on the right track:
$sn=session_name();
error_log("session_name: $sn ");
if(isset($_GET[$sn])) error_log("session as GET param");
if(isset($_POST[$sn])) error_log("session as POST param");
if(isset($_COOKIE[$sn])) error_log("session as Cookie");
if(isset($PHPSESSID)) error_log("session as Global");
A dive into the log and I quickly spotted the missing session, where no cookie was sent.
A LEFT JOIN
is absolutely not faster than an INNER JOIN
. In fact, it's slower; by definition, an outer join (LEFT JOIN
or RIGHT JOIN
) has to do all the work of an INNER JOIN
plus the extra work of null-extending the results. It would also be expected to return more rows, further increasing the total execution time simply due to the larger size of the result set.
(And even if a LEFT JOIN
were faster in specific situations due to some difficult-to-imagine confluence of factors, it is not functionally equivalent to an INNER JOIN
, so you cannot simply go replacing all instances of one with the other!)
Most likely your performance problems lie elsewhere, such as not having a candidate key or foreign key indexed properly. 9 tables is quite a lot to be joining so the slowdown could literally be almost anywhere. If you post your schema, we might be able to provide more details.
Edit:
Reflecting further on this, I could think of one circumstance under which a LEFT JOIN
might be faster than an INNER JOIN
, and that is when:
Consider this example:
CREATE TABLE #Test1
(
ID int NOT NULL PRIMARY KEY,
Name varchar(50) NOT NULL
)
INSERT #Test1 (ID, Name) VALUES (1, 'One')
INSERT #Test1 (ID, Name) VALUES (2, 'Two')
INSERT #Test1 (ID, Name) VALUES (3, 'Three')
INSERT #Test1 (ID, Name) VALUES (4, 'Four')
INSERT #Test1 (ID, Name) VALUES (5, 'Five')
CREATE TABLE #Test2
(
ID int NOT NULL PRIMARY KEY,
Name varchar(50) NOT NULL
)
INSERT #Test2 (ID, Name) VALUES (1, 'One')
INSERT #Test2 (ID, Name) VALUES (2, 'Two')
INSERT #Test2 (ID, Name) VALUES (3, 'Three')
INSERT #Test2 (ID, Name) VALUES (4, 'Four')
INSERT #Test2 (ID, Name) VALUES (5, 'Five')
SELECT *
FROM #Test1 t1
INNER JOIN #Test2 t2
ON t2.Name = t1.Name
SELECT *
FROM #Test1 t1
LEFT JOIN #Test2 t2
ON t2.Name = t1.Name
DROP TABLE #Test1
DROP TABLE #Test2
If you run this and view the execution plan, you'll see that the INNER JOIN
query does indeed cost more than the LEFT JOIN
, because it satisfies the two criteria above. It's because SQL Server wants to do a hash match for the INNER JOIN
, but does nested loops for the LEFT JOIN
; the former is normally much faster, but since the number of rows is so tiny and there's no index to use, the hashing operation turns out to be the most expensive part of the query.
You can see the same effect by writing a program in your favourite programming language to perform a large number of lookups on a list with 5 elements, vs. a hash table with 5 elements. Because of the size, the hash table version is actually slower. But increase it to 50 elements, or 5000 elements, and the list version slows to a crawl, because it's O(N) vs. O(1) for the hashtable.
But change this query to be on the ID
column instead of Name
and you'll see a very different story. In that case, it does nested loops for both queries, but the INNER JOIN
version is able to replace one of the clustered index scans with a seek - meaning that this will literally be an order of magnitude faster with a large number of rows.
So the conclusion is more or less what I mentioned several paragraphs above; this is almost certainly an indexing or index coverage problem, possibly combined with one or more very small tables. Those are the only circumstances under which SQL Server might sometimes choose a worse execution plan for an INNER JOIN
than a LEFT JOIN
.
By default is private
. Unless they're nested, classes are internal
.
cat >> filename
This is text, perhaps pasted in from some other source.
Or else entered at the keyboard, doesn't matter.
^D
Essentially, you can dump any text you want into the file. CTRL-D sends an end-of-file signal, which terminates input and returns you to the shell.
In projects that use the Gradle build system, what you want to change is the applicationId
in the build.gradle file. The build system uses this value to override anything specified by hand in the manifest file when it does the manifest merge and build.
For example, your module's build.gradle file looks something like this:
apply plugin: 'com.android.application'
android {
compileSdkVersion 20
buildToolsVersion "20.0.0"
defaultConfig {
// CHANGE THE APPLICATION ID BELOW
applicationId "com.example.fred.myapplication"
minSdkVersion 10
targetSdkVersion 20
versionCode 1
versionName "1.0"
}
}
applicationId
is the name the build system uses for the property that eventually gets written to the package
attribute of the manifest
tag in the manifest file. It was renamed to prevent confusion with the Java package name (which you have also tried to modify), which has nothing to do with it.
you mean:
SELECT * FROM items WHERE items.xml LIKE '%123456%'
You can just use String.ToCharArray() and then treat each char as a string in your code.
Here's an example:
foreach (char c in s.ToCharArray())
Debug.Log("one character ... " +c);
Apparently, there's a lot of "dead wood" in the "build" directories of a project.
Under linux/unix, a simple way to get a clean, private backup is to use the "tar" command along with the "--exclude=String" option.
For example, to create an archive of all my apps while excluding the build directories, I have a script that creates the following 2 commands :
cd $HOME/android/Studio
tar cvf MyBackup-2017-07-13.tar Projects --exclude=build
The Html.Hidden creates a hidden input but you have to specify the name and all the attributes you want to give that field and value. The Html.HiddenFor
creates a hidden input for the object that you pass to it, they look like this:
Html.Hidden("yourProperty",model.yourProperty);
Html.HiddenFor(m => m.yourProperty)
In this case the output is the same!
I have had this issue before and it turned out that Skype was interferring with port 80. So you may have to look at your system to see if you have another application utilizing this port.
Anyway under Skype, to change this setting it was: Tools->Options->Advanced->Connection->Use port 80 and 443 as alternatives for incoming connections
. Untick this, restart Skype, restart wamp.
I'm a bit late to the party, but here's a bit of jQuery I've been using:
$('.carousel').on('touchstart', function(event){
const xClick = event.originalEvent.touches[0].pageX;
$(this).one('touchmove', function(event){
const xMove = event.originalEvent.touches[0].pageX;
const sensitivityInPx = 5;
if( Math.floor(xClick - xMove) > sensitivityInPx ){
$(this).carousel('next');
}
else if( Math.floor(xClick - xMove) < -sensitivityInPx ){
$(this).carousel('prev');
}
});
$(this).on('touchend', function(){
$(this).off('touchmove');
});
});
No need for jQuery mobile or any other plugins. If you need to adjust the sensitivity of the swipe adjust the 5
and -5
. Hope this helps someone.
This command loads class of Oracle jdbc driver to be available for DriverManager instance. After the class is loaded system can connect to Oracle using it. As an alternative you can use registerDriver method of DriverManager and pass it with instance of JDBC driver you need.
Yeah, But not in a normal way. You will have to use switch as closure.
ex:-
function test(input1, input2) {
switch (true) {
case input1 > input2:
console.log(input1 + " is larger than " + input2);
break;
case input1 < input2:
console.log(input2 + " is larger than " + input1);
default:
console.log(input1 + " is equal to " + input2);
}
}
The problem is your query returned false
meaning there was an error in your query. After your query you could do the following:
if (!$result) {
die(mysqli_error($link));
}
Or you could combine it with your query:
$results = mysqli_query($link, $query) or die(mysqli_error($link));
That will print out your error.
Also... you need to sanitize your input. You can't just take user input and put that into a query. Try this:
$query = "SELECT * FROM shopsy_db WHERE name LIKE '%" . mysqli_real_escape_string($link, $searchTerm) . "%'";
In reply to: Table 'sookehhh_shopsy_db.sookehhh_shopsy_db' doesn't exist
Are you sure the table name is sookehhh_shopsy_db? maybe it's really like users or something.
EDIT :
The implementation of a Singleton in Android is not "safe" (see here) and you should use a library dedicated to this kind of pattern like Dagger or other DI library to manage the lifecycle and the injection.
Could you post an example from your code ?
Take a look at this gist : https://gist.github.com/Akayh/5566992
it works but it was done very quickly :
MyActivity : set the singleton for the first time + initialize mString attribute ("Hello") in private constructor and show the value ("Hello")
Set new value to mString : "Singleton"
Launch activityB and show the mString value. "Singleton" appears...
Javascript doesn't have it, as you point out.
A quick search came up with:
function strcmp ( str1, str2 ) {
// http://kevin.vanzonneveld.net
// + original by: Waldo Malqui Silva
// + input by: Steve Hilder
// + improved by: Kevin van Zonneveld (http://kevin.vanzonneveld.net)
// + revised by: gorthaur
// * example 1: strcmp( 'waldo', 'owald' );
// * returns 1: 1
// * example 2: strcmp( 'owald', 'waldo' );
// * returns 2: -1
return ( ( str1 == str2 ) ? 0 : ( ( str1 > str2 ) ? 1 : -1 ) );
}
from http://kevin.vanzonneveld.net/techblog/article/javascript_equivalent_for_phps_strcmp/
Of course, you could just add localeCompare if needed:
if (typeof(String.prototype.localeCompare) === 'undefined') {
String.prototype.localeCompare = function(str, locale, options) {
return ((this == str) ? 0 : ((this > str) ? 1 : -1));
};
}
And use str1.localeCompare(str2)
everywhere, without having to worry wether the local browser has shipped with it. The only problem is that you would have to add support for locales
and options
if you care about that.
You can create with javascript some css-rules
, which you can later use in your styles: http://jsfiddle.net/ARTsinn/vKbda/
var addRule = (function (sheet) {
if(!sheet) return;
return function (selector, styles) {
if (sheet.insertRule) return sheet.insertRule(selector + " {" + styles + "}", sheet.cssRules.length);
if (sheet.addRule) return sheet.addRule(selector, styles);
}
}(document.styleSheets[document.styleSheets.length - 1]));
var i = 101;
while (i--) {
addRule("[data-width='" + i + "%']", "width:" + i + "%");
}
This creates 100 pseudo-selectors like this:
[data-width='1%'] { width: 1%; }
[data-width='2%'] { width: 2%; }
[data-width='3%'] { width: 3%; }
...
[data-width='100%'] { width: 100%; }
Note: This is a bit offtopic, and not really what you (or someone) wants, but maybe helpful.
Here is a side note for some that may be searching this thread for an answer to this problem. (Be sure to read cautions at the bottom before implementing this solution.) I was having trouble sending emails for a client to which my MS Office 365 subscription did not have a user or domain for. I was trying to SMTP through my [email protected] 365 account but the .NET mail message was addressed from [email protected]. This is when the "5.7.1 Client does not have permissions" error popped up for me. To remedy, the MailMessage class needed to have the Sender property set to an email address that my supplied SMTP credentials had permission in O365 to "Send As". I chose to use my main account email ([email protected]) as seen in the code below. Keep in mind I could have used ANY email address my O365 account had permission to "send as" (i.e. [email protected], [email protected], etc.)
using System;
using System.Net.Mail;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
using (
MailMessage message = new MailMessage
{
To = { new MailAddress("[email protected]", "Recipient 1") },
Sender = new MailAddress("[email protected]", "Me"),
From = new MailAddress("[email protected]", "Client"),
Subject=".net Testing"
Body="Testing .net emailing",
IsBodyHtml=true,
}
)
{
using (
SmtpClient smtp = new SmtpClient
{
Host = "smtp.office365.com",
Port = 587,
Credentials = new System.Net.NetworkCredential("[email protected]", "Pa55w0rd"),
EnableSsl = true
}
)
{
try { smtp.Send(message); }
catch (Exception excp)
{
Console.Write(excp.Message);
Console.ReadKey();
}
}
}
}
}
}
Please note SmtpClient is only disposable and able to use the Using block in .NET Framework 4
Users of .NET Framework 2 through 3.5 should use SmtpClient as such...
SmtpClient smtp = new SmtpClient
{
Host = "smtp.office365.com",
Port = 587,
Credentials = new System.Net.NetworkCredential("[email protected]", "Pa55w0rd"),
EnableSsl = true
};
try { smtp.Send(message); }
catch (Exception excp)
{
Console.Write(excp.Message);
Console.ReadKey();
}
The resulting email's header will look something like this:
Authentication-Results: spf=none (sender IP is )
[email protected];
Received: from MyPC (192.168.1.1) by
BLUPR13MB0036.namprd13.prod.outlook.com (10.161.123.150) with Microsoft SMTP
Server (TLS) id 15.1.318.9; Mon, 9 Nov 2015 16:06:58 +0000
MIME-Version: 1.0
From: Client <[email protected]>
Sender: Me <[email protected]>
To: Recipient 1 <[email protected]>
-- Be Cautious --
Be aware some mail clients may display the Sender address as a note. For example Outlook will display something along these lines in the Reading Pane's header:
Me <[email protected]> on behalf of Client <[email protected]>
However, so long as the email client the recipient uses isn't total garbage, this shouldn't effect the Reply To address. Reply To should still use the From address. To cover all your bases, you can also utilize the MailMessage.ReplyToList property to afford every opportunity to the client to use the correct reply address.
Also, be aware that some email servers may flat out reject any emails that are Sent On Behalf of another company siting Domain Owner Policy Restrictions. Be sure to test thoroughly and look for any bounce backs. I can tell you that my personal Hotmail (mail.live.com) email account is one that will reject messages I send on behalf of a certain client of mine but others clients go through fine. Although I suspect that it has something to do with my client's domain TXT "spf1" records, I do not have an answer as to why it will reject emails sent on behalf of one domain versus another. Maybe someone who knows can shed some light on the subject?
Suppose
letter= ['a','','b','c']
for i in range(len(letter)):
if letter[i] =='':
print(str(i) + ' is empty')
output- 1 is emtpy
So we can see index 1 is empty.
You can use exec
for that:
>>> foo = "bar"
>>> exec(foo + " = 'something else'")
>>> print bar
something else
>>>
You can also do what the "Service Reference" generated code does
public class ServiceXClient : ClientBase<IServiceX>, IServiceX
{
public ServiceXClient() { }
public ServiceXClient(string endpointConfigurationName) :
base(endpointConfigurationName) { }
public ServiceXClient(string endpointConfigurationName, string remoteAddress) :
base(endpointConfigurationName, remoteAddress) { }
public ServiceXClient(string endpointConfigurationName, EndpointAddress remoteAddress) :
base(endpointConfigurationName, remoteAddress) { }
public ServiceXClient(Binding binding, EndpointAddress remoteAddress) :
base(binding, remoteAddress) { }
public bool ServiceXWork(string data, string otherParam)
{
return base.Channel.ServiceXWork(data, otherParam);
}
}
Where IServiceX is your WCF Service Contract
Then your client code:
var client = new ServiceXClient(new WSHttpBinding(SecurityMode.None), new EndpointAddress("http://localhost:911"));
client.ServiceXWork("data param", "otherParam param");
// define
var foo = {
bar: ['foo', 'bar', 'baz']
};
// access
foo.bar[2]; // will give you 'baz'
Please try this which it works for me.
return [] as Criminal[];
Just execute
sudo npm i --save
That's all
It depends on your file path. For me, the current directory was [project]\bin\Debug
, so I had to move to the parent folder twice.
Image image = Image.FromFile(@"..\..\Pictures\"+text+".png");
this.pictureBox1.Image = image;
To find your current directory, you can make a dummy label called label2 and write this:
this.label2.Text = System.IO.Directory.GetCurrentDirectory();
I have tried these methods and find that they dont work for my needs. In my case, I needed to inject json rendered server side into the main template of the page, so when it loads and angular inits, the data is already there and doesnt have to be retrieved (large dataset).
The easiest solution that I have found is to do the following:
In your angular code outside of the app, module and controller definitions add in a global javascript value - this definition MUST come before the angular stuff is defined.
Example:
'use strict';
//my data variable that I need access to.
var data = null;
angular.module('sample', [])
Then in your controller:
.controller('SampleApp', function ($scope, $location) {
$scope.availableList = [];
$scope.init = function () {
$scope.availableList = data;
}
Finally, you have to init everything (order matters):
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js"></script>
<script src="/path/to/your/angular/js/sample.js"></script>
<script type="text/javascript">
data = <?= json_encode($cproducts); ?>
</script>
Finally initialize your controller and init function.
<div ng-app="samplerrelations" ng-controller="SamplerApp" ng-init="init();">
By doing this you will now have access to whatever data you stuffed into the global variable.
You can use Line height a big as height of the div.
But for me best solution is this --> position:relative; top:50%; transform:translate(0,50%);
object.__del__(self)
is called when the instance is about to be destroyed.
>>> class Test:
... def __del__(self):
... print "deleted"
...
>>> test = Test()
>>> del test
deleted
Object is not deleted unless all of its references are removed(As quoted by ethan)
Also, From Python official doc reference:
del x doesn’t directly call x.del() — the former decrements the reference count for x by one, and the latter is only called when x‘s reference count reaches zero

Add any other allowable non-alphanumeric characters to the middle brackets to allow them to be parsed as well.
Of course it is right what you say at the beginning, and C logical operator &&
and ||
are what you usually use to "connect" conditions (expressions that can be evaluated as true or false); the comma operator is not a logical operator and its use in that example makes no sense, as explained by other users. You can use it e.g. to "concatenate" statements in the for itself: you can initialize and update j altogether with i; or use the comma operator in other ways
#include <stdio.h>
int main(void) // as std wants
{
int i, j;
// init both i and j; condition, we suppose && is the "original"
// intention; update i and j
for(i=0, j=2; j>=0 && i<=5; i++, j--)
{
printf("%d ", i+j);
}
return 0;
}
Add the following css class
.dropdown-menu {
width: 300px !important;
height: 400px !important;
}
Of course you can use what matches your need.
I ran into this problem yesterday, so I created a React-friendly solution.
Check out react-native-listener. It's working very well so far. Feedback appreciated.
I had this issue for dependencies that were created in other projects. Downloaded thirdparty dependencies showed up fine in the build path, but not a library that I had created.
SOLUTION: In the project that is not building correctly, right-click on the project and choose Properties, and then Maven. Uncheck the box labeled "Resolve dependencies from Workspace projects", hit Apply, and then OK. Right-click again on your project and do a Maven->Update Snapshots (or Update Dependencies) and your errors should go away when your project rebuilds (automatically if you have auto-build enabled).
The accepted answer did not work for me. The Date returned is always the local Date and not the Date for the original Time Zone. I live in UTC+2.
//This did not work for me
Date.from(java.time.ZonedDateTime.now().toInstant());
I have come up with two alternative ways to get the correct Date from a ZonedDateTime.
Say you have this ZonedDateTime for Hawaii
LocalDateTime ldt = LocalDateTime.now();
ZonedDateTime zdt = ldt.atZone(ZoneId.of("US/Hawaii"); // UTC-10
or for UTC as asked originally
Instant zulu = Instant.now(); // GMT, UTC+0
ZonedDateTime zdt = zulu.atZone(ZoneId.of("UTC"));
Alternative 1
We can use java.sql.Timestamp. It is simple but it will probably also make a dent in your programming integrity
Date date1 = Timestamp.valueOf(zdt.toLocalDateTime());
Alternative 2
We create the Date from millis (answered here earlier). Note that local ZoneOffset is a must.
ZoneOffset localOffset = ZoneOffset.systemDefault().getRules().getOffset(LocalDateTime.now());
long zonedMillis = 1000L * zdt.toLocalDateTime().toEpochSecond(localOffset) + zdt.toLocalDateTime().getNano() / 1000000L;
Date date2 = new Date(zonedMillis);
I Created this simple program to get HSV Codes in realtime
import cv2
import numpy as np
cap = cv2.VideoCapture(0)
def nothing(x):
pass
# Creating a window for later use
cv2.namedWindow('result')
# Starting with 100's to prevent error while masking
h,s,v = 100,100,100
# Creating track bar
cv2.createTrackbar('h', 'result',0,179,nothing)
cv2.createTrackbar('s', 'result',0,255,nothing)
cv2.createTrackbar('v', 'result',0,255,nothing)
while(1):
_, frame = cap.read()
#converting to HSV
hsv = cv2.cvtColor(frame,cv2.COLOR_BGR2HSV)
# get info from track bar and appy to result
h = cv2.getTrackbarPos('h','result')
s = cv2.getTrackbarPos('s','result')
v = cv2.getTrackbarPos('v','result')
# Normal masking algorithm
lower_blue = np.array([h,s,v])
upper_blue = np.array([180,255,255])
mask = cv2.inRange(hsv,lower_blue, upper_blue)
result = cv2.bitwise_and(frame,frame,mask = mask)
cv2.imshow('result',result)
k = cv2.waitKey(5) & 0xFF
if k == 27:
break
cap.release()
cv2.destroyAllWindows()
Configure your webserver to send caching control HTTP headers for the script.

Some rules of thumb for subprocess
.
shell=True
. It needlessly invokes an extra shell process to call your program.sys.argv
in python is a list, and so is argv
in C. So you pass a list to Popen
to call subprocesses, not a string.stderr
to a PIPE
when you're not reading it. stdin
when you're not writing to it.Example:
import subprocess, time, os, sys
cmd = ["rsync.exe", "-vaz", "-P", "source/" ,"dest/"]
p = subprocess.Popen(cmd,
stdout=subprocess.PIPE,
stderr=subprocess.STDOUT)
for line in iter(p.stdout.readline, b''):
print(">>> " + line.rstrip())
That said, it is probable that rsync buffers its output when it detects that it is connected to a pipe instead of a terminal. This is the default behavior - when connected to a pipe, programs must explicitly flush stdout for realtime results, otherwise standard C library will buffer.
To test for that, try running this instead:
cmd = [sys.executable, 'test_out.py']
and create a test_out.py
file with the contents:
import sys
import time
print ("Hello")
sys.stdout.flush()
time.sleep(10)
print ("World")
Executing that subprocess should give you "Hello" and wait 10 seconds before giving "World". If that happens with the python code above and not with rsync
, that means rsync
itself is buffering output, so you are out of luck.
A solution would be to connect direct to a pty
, using something like pexpect
.
While SimpleXML provides a way to remove XML nodes, its modification capabilities are somewhat limited. One other solution is to resort to using the DOM extension. dom_import_simplexml() will help you with converting your SimpleXMLElement
into a DOMElement
.
Just some example code (tested with PHP 5.2.5):
$data='<data>
<seg id="A1"/>
<seg id="A5"/>
<seg id="A12"/>
<seg id="A29"/>
<seg id="A30"/>
</data>';
$doc=new SimpleXMLElement($data);
foreach($doc->seg as $seg)
{
if($seg['id'] == 'A12') {
$dom=dom_import_simplexml($seg);
$dom->parentNode->removeChild($dom);
}
}
echo $doc->asXml();
outputs
<?xml version="1.0"?>
<data><seg id="A1"/><seg id="A5"/><seg id="A29"/><seg id="A30"/></data>
By the way: selecting specific nodes is much more simple when you use XPath (SimpleXMLElement->xpath):
$segs=$doc->xpath('//seq[@id="A12"]');
if (count($segs)>=1) {
$seg=$segs[0];
}
// same deletion procedure as above
To use AWK to cut off the first and last fields:
awk '{$1 = ""; $NF = ""; print}' inputfile
Unfortunately, that leaves the field separators, so
aaa bbb ccc
becomes
[space]bbb[space]
To do this using kurumi's answer which won't leave extra spaces, but in a way that's specific to your requirements:
awk '{delim = ""; for (i=2;i<=NF-1;i++) {printf delim "%s", $i; delim = OFS}; printf "\n"}' inputfile
This also fixes a couple of problems in that answer.
To generalize that:
awk -v skipstart=1 -v skipend=1 '{delim = ""; for (i=skipstart+1;i<=NF-skipend;i++) {printf delim "%s", $i; delim = OFS}; printf "\n"}' inputfile
Then you can change the number of fields to skip at the beginning or end by changing the variable assignments at the beginning of the command.
You can handle this without requiring a user input.
Step 1. Create a ManualRestEvent at the start of Main thread
ManualResetEvent manualResetEvent = new ManualResetEvent(false);
Step 2 . Wait ManualResetEvent
manualResetEvent.WaitOne();
Step 3.To Stop
manualResetEvent.Set();
Does it absolutely have to be 100% functional and fluent? If not, how about this, which is about as short as it gets:
Map<String, Integer> output = new HashMap<>();
input.forEach((k, v) -> output.put(k, Integer.valueOf(v));
(if you can live with the shame and guilt of combining streams with side-effects)
Use <td valign="top" style="width: 259px">
instead...
With Swift 5, according to your needs, you may choose one of the following Playground sample codes in order to solve your problem.
Character
s into a String
with no separator:let characterArray: [Character] = ["J", "o", "h", "n"]
let string = String(characterArray)
print(string)
// prints "John"
String
s into a String
with no separator:let stringArray = ["Bob", "Dan", "Bryan"]
let string = stringArray.joined(separator: "")
print(string) // prints: "BobDanBryan"
String
s into a String
with a separator between words:let stringArray = ["Bob", "Dan", "Bryan"]
let string = stringArray.joined(separator: " ")
print(string) // prints: "Bob Dan Bryan"
String
s into a String
with a separator between characters:let stringArray = ["car", "bike", "boat"]
let characterArray = stringArray.flatMap { $0 }
let stringArray2 = characterArray.map { String($0) }
let string = stringArray2.joined(separator: ", ")
print(string) // prints: "c, a, r, b, i, k, e, b, o, a, t"
Float
s into a String
with a separator between numbers:let floatArray = [12, 14.6, 35]
let stringArray = floatArray.map { String($0) }
let string = stringArray.joined(separator: "-")
print(string)
// prints "12.0-14.6-35.0"
The solution for this problem is just to add overflow: auto;
to the .content for making the content wrapper scrollable.
Furthermore, there are circumstances occurring along with Flexbox wrapper and overflowed
scrollable content like this codepen.
The solution is to add overflow: hidden (or auto);
to the parent of the wrapper (set with overflow: auto;) around large contents.
You should take a look the reference documentation. It's well explained.
In your case, I think you cannot use between because you need to pass two parameters
Between - findByStartDateBetween … where x.startDate between ?1 and ?2
In your case take a look to use a combination of LessThan
or LessThanEqual
with GreaterThan
or GreaterThanEqual
LessThan - findByEndLessThan … where x.start< ?1
LessThanEqual findByEndLessThanEqual … where x.start <= ?1
GreaterThan - findByStartGreaterThan … where x.end> ?1
GreaterThanEqual - findByStartGreaterThanEqual … where x.end>= ?1
You can use the operator And
and Or
to combine both.
There is another option: with
syntax. To use the OPs example, this would look like:
with data as (
select 'value1' name from dual
union all
select 'value2' name from dual
union all
...
select 'value10000+' name from dual)
select field1, field2, field3
from table1 t1
inner join data on t1.name = data.name;
I ran into this problem. In my case I had a list of data in Java where each item had an item_id and a customer_id. I have two tables in the DB with subscriptions to items respective customers. I want to get a list of all subscriptions to the items or to the customer for that item, together with the item id.
I tried three variants:
Option 1: Multiple Selects from Java
Basically, I first
select item_id, token
from item_subs
where (item_id, 0) in ((:item_id_0, 0)...(:item_id_n, 0))
Then
select cus_id, token
from cus_subs
where (cus_id, 0) in ((:cus_id_0, 0)...(:cus_id_n, 0))
Then I build a Map in Java with the cus_id as the key and a list of items as value, and for each found customer subscription I add (to the list returned from the first select) an entry for all relevant items with that item_id. It's much messier code
Option 2: With-syntax
Get everything at once with an SQL like
with data as (
select :item_id_0 item_id, :cus_id_0 cus_id
union all
...
select :item_id_n item_id, :cus_id_n cus_id )
select I.item_id item_id, I.token token
from item_subs I
inner join data D on I.item_id = D.item_id
union all
select D.item_id item_id, C.token token
from cus_subs C
inner join data D on C.cus_id = D.cus_id
Option 3: Temporary table
Create a global temporary table with three fields: rownr (primary key), item_id and cus_id. Insert all the data there then run a very similar select to option 2, but linking in the temporary table instead of the with data
Performance
This is not a fully-scientific performance analysis.
YMMV.
That said, the temporary table option was much slower. As in double so slow. I was getting 14-15 seconds for option 1, 15-16 for option 2 and 30 for option 3.
I'll try them again from the same network as the DB server and check if that changes things when I get the chance.
i Did it, just follow this tutorial. helps a lot

Typically with Angular you would be outputting these spans using the ngRepeat directive and (like in your case) each item would have an id. I know this is not true for all situations but it is typical if requesting data from a backend - objects in an array tend to have unique identifiers.
You can use this id to facilitate the toggling of classes on items in your list (see plunkr or code below).
Using the objects id's can also eliminate the undesirable effect when the $index (described in other answers) is messed up due to sorting in Angular.
Example Plunkr: http://plnkr.co/edit/na0gUec6cdMABK9L6drV
(basically apply the .active-selection class if the person.id is equal to $scope.activeClass - which we set when the user clicks an item.
Hope this helps someone, I've found expressions in ng-class to be very useful!
HTML
<ul>
<li ng-repeat="person in people"
data-ng-class="{'active-selection': person.id == activeClass}">
<a data-ng-click="selectPerson(person.id)">
{{person.name}}
</a>
</li>
</ul>
JS
app.controller('MainCtrl', function($scope) {
$scope.people = [{
id: "1",
name: "John",
}, {
id: "2",
name: "Lucy"
}, {
id: "3",
name: "Mark"
}, {
id: "4",
name: "Sam"
}];
$scope.selectPerson = function(id) {
$scope.activeClass = id;
console.log(id);
};
});
CSS:
.active-selection {
background-color: #eee;

Solution 1 : One solution that worked for me when this error "The declared package does not match the expected package" occured for a project I checked-out from eclipse CVS :
1.Right click the project in the navigation bar and click 'delete'
2.Make sure 'Delete project contents on disk' option is NOT checked, and click OK.
3.Now after the project is deleted, go to File -> Import -> General -> Existing Projects into Workspace
4.Select your workspace from the directory listing and check the box next to your project name. Click 'Finish'
Solution 2 : Once again I got this error with the following message
Eclipse build errors - java.lang.Object cannot be resolved I had to follow another route mention here and the error went away.
In the mean time, the work around is to remove the JRE System Library from the project and then add it back again. Here are the steps:
Hopefully the error will be resolved ...
checked the program and the results are as,
p++; // use it then move to next int position
++p; // move to next int and then use it
++*p; // increments the value by 1 then use it
++(*p); // increments the value by 1 then use it
++*(p); // increments the value by 1 then use it
*p++; // use the value of p then moves to next position
(*p)++; // use the value of p then increment the value
*(p)++; // use the value of p then moves to next position
*++p; // moves to the next int location then use that value
*(++p); // moves to next location then use that value
I guess you could try
table tr td { color: red; }
table tr td table tr td { color: black; }
Or
body table tr td { color: red; }
where 'body' is a selector for your table's parent
But classes are most likely the right way to go here.
var x = $('#h_v').val();
alert(x);

I made this for a webservice to requerst on URL, using a Gson lib:
Client:
public EstabelecimentoList getListaEstabelecimentoPorPromocao(){
EstabelecimentoList estabelecimentoList = new EstabelecimentoList();
try{
URL url = new URL("http://" + Conexao.getSERVIDOR()+ "/cardapio.online/rest/recursos/busca_estabelecimento_promocao_android");
HttpURLConnection con = (HttpURLConnection) url.openConnection();
if (con.getResponseCode() != 200) {
throw new RuntimeException("HTTP error code : "+ con.getResponseCode());
}
BufferedReader br = new BufferedReader(new InputStreamReader((con.getInputStream())));
estabelecimentoList = new Gson().fromJson(br, EstabelecimentoList.class);
con.disconnect();
} catch (IOException e) {
e.printStackTrace();
}
return estabelecimentoList;
}
The only reason that the linter complains about using setState({..})
in componentDidMount
and componentDidUpdate
is that when the component render the setState immediately causes the component to re-render.
But the most important thing to note: using it inside these component's lifecycles is not an anti-pattern in React.
Please take a look at this issue. you will understand more about this topic. Thanks for reading my answer.

here's a short paragraph from this article How to Make Frames (Main Windows) - The Java Tutorials - Oracle that explains what setBounds method does in addition to some other similar methods:
The pack method sizes the frame so that all its contents are at or above their preferred sizes. An alternative to pack is to establish a frame size explicitly by calling setSize or setBounds (which also sets the frame location). In general, using pack is preferable to calling setSize, since pack leaves the frame layout manager in charge of the frame size, and layout managers are good at adjusting to platform dependencies and other factors that affect component size.
the parameters of setBounds are (int x, int y, int width, int height) x and y are define the position/location and width and height define the size/dimension of the frame.
as long as it's a variable and not a second class, this here works for me:
def print_var_name(variable):
for name in globals():
if eval(name) == variable:
print name
foo = 123
print_var_name(foo)
>>>foo
this happens for class members:
class xyz:
def __init__(self):
pass
member = xyz()
print_var_name(member)
>>>member
ans this for classes (as example):
abc = xyz
print_var_name(abc)
>>>abc
>>>xyz
So for classes it gives you the name AND the properteries
The first answer is great only for those people who know kotlin, for those who still using java here I translate the first answer

For android, P don't forget to include this permission
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
First things first, you need to loop to < a.length
rather than a.length - 1
. As this is strictly less than you need to include the upper bound.
So, to check all pairs of elements you can do:
for (int i = 0; i < a.length; i++) {
for (int k = 0; k < a.length; k++) {
if (a[i] != a[k]) {
//do stuff
}
}
}
But this will compare, for example a[2]
to a[3]
and then a[3]
to a[2]
. Given that you are checking !=
this seems wasteful.
A better approach would be to compare each element i
to the rest of the array:
for (int i = 0; i < a.length; i++) {
for (int k = i + 1; k < a.length; k++) {
if (a[i] != a[k]) {
//do stuff
}
}
}
So if you have the indices [1...5] the comparison would go
1 -> 2
1 -> 3
1 -> 4
1 -> 5
2 -> 3
2 -> 4
2 -> 5
3 -> 4
3 -> 5
4 -> 5
So you see pairs aren't repeated. Think of a circle of people all needing to shake hands with each other.
You can just use the TimeOfDay property of date time, which is TimeSpan type:
DateTime.TimeOfDay
This property has been around since .NET 1.1
More information: http://msdn.microsoft.com/en-us/library/system.datetime.timeofday(v=vs.110).aspx
.. you can cleanup your nested fragment in the parent fragment's destroyview
method:
@Override
public void onDestroyView() {
try{
FragmentTransaction transaction = getSupportFragmentManager()
.beginTransaction();
transaction.remove(nestedFragment);
transaction.commit();
}catch(Exception e){
}
super.onDestroyView();
}
If the primary key happens to be an auto_increment value, you have to remove the auto increment, then drop the primary key then re-add the auto-increment
ALTER TABLE `xx`
MODIFY `auto_increment_field` INT,
DROP PRIMARY KEY,
ADD PRIMARY KEY (new_primary_key);
then add back the auto increment
ALTER TABLE `xx` ADD INDEX `auto_increment_field` (auto_increment_field),
MODIFY `auto_increment_field` int auto_increment;
then set auto increment back to previous value
ALTER TABLE `xx` AUTO_INCREMENT = 5;
Since Mockito 2.0 there's also possibility to use static method Matchers.argThat(ArgumentMatcher). With the help of Java 8 it is now much cleaner and more readable to write:
verify(mockBar).doSth(argThat((arg) -> arg.getSurname().equals("OneSurname")));
verify(mockBar).doSth(argThat((arg) -> arg.getSurname().equals("AnotherSurname")));
If you're tied to lower Java version there's also not-that-bad:
verify(mockBar).doSth(argThat(new ArgumentMatcher<Employee>() {
@Override
public boolean matches(Object emp) {
return ((Employee) emp).getSurname().equals("SomeSurname");
}
}));
Of course none of those can verify order of calls - for which you should use InOrder :
InOrder inOrder = inOrder(mockBar);
inOrder.verify(mockBar).doSth(argThat((arg) -> arg.getSurname().equals("FirstSurname")));
inOrder.verify(mockBar).doSth(argThat((arg) -> arg.getSurname().equals("SecondSurname")));
Please take a look at mockito-java8 project which makes possible to make calls such as:
verify(mockBar).doSth(assertArg(arg -> assertThat(arg.getSurname()).isEqualTo("Surname")));
Not what you asked for, but I do this because of a focus bug in WebKit with spinboxes:
// temporary fix for focus bug with webkit input type=number ui
if (navigator.userAgent.indexOf("AppleWebKit") > -1 && navigator.userAgent.indexOf("Mobile") == -1)
{
var els = document.querySelectorAll("input[type=number]");
for (var el in els)
el.type = "text";
}
It might give you an idea to help with what you need.
For bash scripts this would be the easiest way:
# In the form major.minor.micro e.g. '3.6.8'
# The second part excludes the 'Python ' prefix
PYTHON_VERSION=`python3 --version | awk '{print $2}'`
echo "python3 version: ${PYTHON_VERSION}"
python3 version: 3.6.8
And if you just need the major.minor
version (e.g. 3.6
) you can either use the above and then pick the first 3 characters:
PYTHON_VERSION=`python3 --version | awk '{print $2}'`
echo "python3 major.minor: ${PYTHON_VERSION:0:3}"
python3 major.minor: 3.6
or
PYTHON_VERSION=`python3 -c 'import sys; print(str(sys.version_info[0])+"."+str(sys.version_info[1]))'`
echo "python3 major.minor: ${PYTHON_VERSION}"
python3 major.minor: 3.6
Simply,
$res = (object)array("success"=>false); // $res->success = bool(false);
Or you could instantiate classes with:
$res = (object)array(); // object(stdClass) -> recommended
$res = (object)[]; // object(stdClass) -> works too
$res = new \stdClass(); // object(stdClass) -> old method
and fill values with:
$res->success = !!0; // bool(false)
$res->success = false; // bool(false)
$res->success = (bool)0; // bool(false)

Edit: in lieu of my own answer, this one is quite excellent: How to debug JavaScript/jQuery event bindings with Firebug (or similar tool)
Google Chromes developer tools has a search function built into the scripts section
If you are unfamiliar with this tool: (just in case)
Doing a quick search for the #ID should take you to the binding function eventually.
Ex: searching for #foo
would take you to
$('#foo').click(function(){ alert('bar'); })
@HTML.ActionLink
generates a HTML anchor tag
. While @Url.Action
generates a URL
for you. You can easily understand it by;
// 1. <a href="/ControllerName/ActionMethod">Item Definition</a>
@HTML.ActionLink("Item Definition", "ActionMethod", "ControllerName")
// 2. /ControllerName/ActionMethod
@Url.Action("ActionMethod", "ControllerName")
// 3. <a href="/ControllerName/ActionMethod">Item Definition</a>
<a href="@Url.Action("ActionMethod", "ControllerName")"> Item Definition</a>
Both of these approaches are different and it totally depends upon your need.
var classList = $(element).attr('class').split(/\s+/);

I just wondered, why col-xs-6
did not work for me but then I found the answer in the Bootstrap 4 documentation. The class prefix for extra small devices is now col-
while in the previous versions it was col-xs
.
https://getbootstrap.com/docs/4.1/layout/grid/#grid-options
Bootstrap 4 dropped all col-xs-*
classes, so use col-*
instead. For example col-xs-6
replaced by col-6
.
i used bootstrap in a press site but it does not worked on IE8, i used css3-mediaqueries.js javascript but still not working. if you want your media query to work with this javascript file add screen to your media query line in css
here is an example :
<meta name="viewport" content="width=device-width" />
<style>
@media screen and (max-width:900px) {}
@media screen and (min-width:900px) and (max-width:1200px) {}
@media screen and (min-width:1200px) {}
</style>
<link rel="stylesheet" type="text/css" href="bootstrap.min.css">

I personally favour this syntax, which uses the explicit IsDbNull method exposed by IDataRecord
, and caches the column index to avoid a duplicate string lookup.
Expanded for readability, it goes something like:
int columnIndex = row.GetOrdinal("Foo");
string foo; // the variable we're assigning based on the column value.
if (row.IsDBNull(columnIndex)) {
foo = String.Empty; // or whatever
} else {
foo = row.GetString(columnIndex);
}
Rewritten to fit on a single line for compactness in DAL code - note that in this example we're assigning int bar = -1
if row["Bar"]
is null.
int i; // can be reused for every field.
string foo = (row.IsDBNull(i = row.GetOrdinal("Foo")) ? null : row.GetString(i));
int bar = (row.IsDbNull(i = row.GetOrdinal("Bar")) ? -1 : row.GetInt32(i));
The inline assignment can be confusing if you don't know it's there, but it keeps the entire operation on one line, which I think enhances readability when you're populating properties from multiple columns in one block of code.
There is a simple concise way, using regex flag (case insensitive {i}):
String s1 = "hello abc efg";
String s2 = "ABC";
s1.matches(".*(?i)"+s2+".*");
/*
* .* denotes every character except line break
* (?i) denotes case insensitivity flag enabled for s2 (String)
* */
Try running,
SELECT SERVERPROPERTY('COLLATION')
Then find out if your collation is case sensitive or not.
You need to remove TFS credentials from Windows Vault to clear and force to ask new TFS credentials in Visual Studio
Go to Control Panel (Start -> Control Panel).
Click User Accounts ( or User Accounts and Family Safety->User Accounts in Windows 7 Machine)
Click Credential Manager (or Manage your credentials)
In Credential Manager page, you can see the two type of credentials
i. Windows Credentials
ii. Generic Credentials
5.Click on two credentials modify link, click the link Remove from vault to remove stored TFS credentials.
Now, When you login into Visual Studio you will be asked to give credentials to connect TFS.
Note: Don't forgot to uncheck the option Remember my credentials to force to ask credentials for every TFS connections.
Something like
select *
from foo
where regexp_like( col1, '[^[:alpha:]]' ) ;
should work
SQL> create table foo( col1 varchar2(100) );
Table created.
SQL> insert into foo values( 'abc' );
1 row created.
SQL> insert into foo values( 'abc123' );
1 row created.
SQL> insert into foo values( 'def' );
1 row created.
SQL> select *
2 from foo
3 where regexp_like( col1, '[^[:alpha:]]' ) ;
COL1
--------------------------------------------------------------------------------
abc123
@Mayur "4.2 [Using query with complex JOIN]" with Common Table Expressions (CTEs) did the trick for me.
WITH cte AS (
SELECT e.id, e.postcode
FROM employees e
LEFT JOIN locations lc ON lc.postcode=cte.postcode
WHERE e.id=1
)
UPDATE employee_location SET lat=lc.lat, longitude=lc.longi
FROM cte
WHERE employee_location.id=cte.id;
Hope this helps... :D
For PowerShell 5.1, enable this setting:
Control Panel, Region, Administrative, Change system locale, Use Unicode UTF-8 for worldwide language support
Then enter this into PowerShell:
$PSDefaultParameterValues['*:Encoding'] = 'Default'
Alternatively, you can upgrade to PowerShell 6 or higher.
You can work out the columns that are only in one DataFrame and use this to select a subset of columns in the merge.
cols_to_use = df2.columns.difference(df.columns)
Then perform the merge (note this is an index object but it has a handy tolist()
method).
dfNew = merge(df, df2[cols_to_use], left_index=True, right_index=True, how='outer')
This will avoid any columns clashing in the merge.
The string
class has a constructor that takes a NULL-terminated C-string:
char arr[ ] = "This is a test";
string str(arr);
// You can also assign directly to a string.
str = "This is another string";
// or
str = arr;
try
Dialog dialog=new Dialog(this,android.R.style.Theme_Black_NoTitleBar_Fullscreen)
This will probably have some performance costs when creating the connection but as connections are pooled, they are created only once and then reused, so it won't make any difference to your application. But as always: measure it.
UPDATE:
There are two authentication modes:
This is problem resulting from lack of SNI(Server Name Identification) support inA,ndroid 2.x. I was struggling with this problem for a week until I came across the following question, which not only gives a good background of the problem but also provides a working and effective solution devoid of any security holes.
Verify(a).aFunc(eq(b))
In pseudocode:
When in the instance
a
- a function namedaFunc
is called.Verify this call got an argument which is equal to
b
.
Here's how I find valid 10-digit US phone numbers. At this point I'm assuming the user wants my content so the numbers themselves are trusted. I'm using in an app that ultimately sends an SMS message so I just want the raw numbers no matter what. Formatting can always be added later
//eliminate every char except 0-9
$justNums = preg_replace("/[^0-9]/", '', $string);
//eliminate leading 1 if its there
if (strlen($justNums) == 11) $justNums = preg_replace("/^1/", '',$justNums);
//if we have 10 digits left, it's probably valid.
if (strlen($justNums) == 10) $isPhoneNum = true;
Edit: I ended up having to port this to Java, if anyone's interested. It runs on every keystroke so I tried to keep it fairly light:
boolean isPhoneNum = false;
if (str.length() >= 10 && str.length() <= 14 ) {
//14: (###) ###-####
//eliminate every char except 0-9
str = str.replaceAll("[^0-9]", "");
//remove leading 1 if it's there
if (str.length() == 11) str = str.replaceAll("^1", "");
isPhoneNum = str.length() == 10;
}
Log.d("ISPHONENUM", String.valueOf(isPhoneNum));
First you must create an empty figure with the following command.
figure('name','Title of the window here');
By doing this, the newly created figure becomes you active figure. Immediately after calling a plot()
command, it will print your plotting onto this figure. So your window will have a title.
This is the code you must use:
figure('name','Title of the window here');

The move
instruction copies a value from one register to another. The li
instruction loads a specific numeric value into that register.
For the specific case of zero, you can use either the constant zero or the zero register to get that:
move $s0, $zero
li $s0, 0
There's no register that generates a value other than zero, though, so you'd have to use li
if you wanted some other number, like:
li $s0, 12345678
I think you need to do is to transform your data from object not to JSON string, but to url params.
By default, the $http service will transform the outgoing request by serializing the data as JSON and then posting it with the content- type, "application/json". When we want to post the value as a FORM post, we need to change the serialization algorithm and post the data with the content-type, "application/x-www-form-urlencoded".
Example from here.
$http({
method: 'POST',
url: url,
headers: {'Content-Type': 'application/x-www-form-urlencoded'},
transformRequest: function(obj) {
var str = [];
for(var p in obj)
str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]));
return str.join("&");
},
data: {username: $scope.userName, password: $scope.password}
}).then(function () {});
To use new services added with AngularJS V1.4, see
No. Every jQuery function returns a jQuery object, and that is how it works. This is a crucial part of jQuery's magic.
If you want to access the underlying element, you have three options...
[0]
to reference itExtend jQuery to do what you want...
$.fn.child = function(s) {
return $(this).children(s)[0];
}
The S parameter does not do anything on its own.
/S Modifies the treatment of string after /C or /K (see below)
/C Carries out the command specified by string and then terminates
/K Carries out the command specified by string but remains
Try something like this instead
Call Shell("cmd.exe /S /K" & "perl a.pl c:\temp", vbNormalFocus)
You may not even need to add "cmd.exe" to this command unless you want a command window to open up when this is run. Shell should execute the command on its own.
Shell("perl a.pl c:\temp")
-Edit-
To wait for the command to finish you will have to do something like @Nate Hekman shows in his answer here
Dim wsh As Object
Set wsh = VBA.CreateObject("WScript.Shell")
Dim waitOnReturn As Boolean: waitOnReturn = True
Dim windowStyle As Integer: windowStyle = 1
wsh.Run "cmd.exe /S /C perl a.pl c:\temp", windowStyle, waitOnReturn
If You have already updated your SDK and You also using google-play-services then you need to take care of the dependency because there are some kind of conflics with :
Follow the below : compile 'com.google.android.gms:play-services:+' Replace by compile 'com.google.android.gms:play-services:6.5.87'
Note: Here '6.5.87' is the google-play-service version. I hope it will help..
SELECT *, CAST(SUBSTRING_INDEX(field, '-', -1) AS UNSIGNED) as num FROM tableName ORDER BY num;
You can use XDocument.Parse(string)
instead of Load(string)

With jQuery this is working for me :
$('img').error(function() {
$(this).attr('src', '/no-img.png').addClass('no-img');
});
And I can use this picture everywhere on my website regardless of the size of it with the following CSS3 property :
img.no-img {
object-fit: cover;
object-position: 50% 50%;
}
TIP 1 : use a square image of at least 800 x 800 pixels.
TIP 2 : for use with portrait of people, use
object-position: 20% 50%;
For missing background images, I also added the following on each background-image
declaration :
background-image: url('path-to-image.png'), url('no-img.png');
NOTE : not working for transparent images.
Another solution is to detect missing image with Apache before to send to browser and remplace it by the default no-img.png content.
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} /images/.*\.(gif|jpg|jpeg|png)$
RewriteRule .* /images/no-img.png [L,R=307]
